Here are some simple equations that can be a life saver with this stuff :
vol of a sphere =

Circumference =

sorry this might not be very helpful. I haven't don't this since last year. You basically have to work backwards. so plug in 972 for V and then do (3/4)×3.14.
then take the answer u got for ^^ and divide it by 2? not sure.
Answer:
Step-by-step explanation:
57/100 + 3/10
they need common denominators so a common denominator is 100
so 10x10=100 and 3x10= 30 so we now got
57/100 + 30/100 which is 87/100
Answer:
14 = rounded 15
Step-by-step explanation:
What grade r u in?
And what time is where u r?
<u>Answer-</u>

<u>Solution-</u>
As we know that, on the number line, if a number is on the right of another number, then the former number is greater than the later number.
As, the number on the right side are 4, 5, ...so on (4 is dotted so it is included)
So the inequality will be 
As, the number on the left side are -3, -4, -5, ..... so on (-2 is not dotted so it is excluded)
So the inequality will be 
Then the compound inequality will be,
